In house manufacturing facilities at BNML are constantly being added to, presently manufacturing processes covered include:

  • CNC Turning and Milling

    BNML utilise CNC lathes and millers to produce high integrity products, which can be repeated readily, to close tolerances.

    We can manufacture components from M2 – M200 diameter.

  • Conventional Machining

    BNML has conventional machining facilities running alongside CNC machinery, this range of facilities enables us to manufacture a wide range of sizes and also gives us the facility to manufacture smaller quantities of fasteners economically.

  • Hot Forging

    BNML can hot forge bolts, where bar turning would be a less economical method of manufacture, this is generally where quantities are larger.

    Some applications also dictate that we begin with a forged product.

    Bolts with hexagon and socket heads can be hot forged, please contact us for size availability as tooling is constantly being added to.

  • Thread Rolling

    BNML can roll form threads for greater integrity and strength of threadform, where the customer’s specification dictates.

  • Single Point Screw Cutting

    BNML can single point screw cut threads to give an accurate and precise threadform, where the customer’s specification demands this.

  • Broaching

    BNML not only have the facility to broach standard items such as socket heads, but can also manufacture broaching tools in house in non standard forms and sizes to customers’ requirements.

Threaded products from M2 to M200 (or imperial equivalents). We can manufacture up to 6 metres in length.
